SOAP DISPENSER.

App11cation filed January 14, 1926. Serial No. 81,152.

My invention relates to a soap dispensing device that isdesigned to occupy a fixed position above and adjacent to the washbowls in hotels, work rooms, factories, and

the like, land which device when properly manipulated delivers into the hand of the user a small quantity of soap.

The principal objects of my invention are to generally improve upon and simplify the construction of the existing forms of soap dispensers, to provide a device of the character referred to that is relatively simple in construction, capable of being easily and cheaply produced and which, when actuated, will be effective in positively delivering a small amount of relatively soft pastelike soap.

A further object of my invention is .to provide a soap dispenser that has relatively few parts, thereby enabling the device to be manufactured and installed with economy and at the same time minimizing the liability of the device becoming inoperative due to disarrangement of its pperatmg arts. p With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed-and illustrated in the accompanying drawing, in which- Fig. 1. is a perspective view of a soap dispensing device embodying the principles of my-invention.

Referring by numeralsto the accompanying drawing, andparticularly to the form of dispenser shown in Figs. 1 to 4 inclusive, 10

designates a hollow cylindrical container that is preferably formed of metal and which has a fixed bottom 11 and a readily removable cap or cover 12. Axially disposed within this container -and extending through the bottom 11 thereof is a tube 13 that is externally threaded as designated by '14 for the greater portion of its length and said tube is, mounted so that it rotates in its bearing in the bottom plate 11. Said tube is retained for rotary movement within the container by a nut 15 that is screw-seated on that portion of the tube that projects through said bottom 11 and said nut bearing against the under faceof "said bottom.

To retain the nut 15 on the tubular member 13, a lock nut 16 is seated on a threaded portion of said tube 13 and bears directly.

against the underside of said nut 15.

While I have shown and described nut 15 as being threaded on the tube 13, it may be pressed thereon. Formed through the wall of tube 14 a short distance above the bottom plate 11 are apertures 17. The upper end of tube 13 is closed by a screw plug 18 through the center of which is formed an aperture 19. The hub portion of a follower or pressure plate 20 is provided with a threaded aperture that receives the threaded tube 13. and the edge of said plate is provided with a flange 21 that engages the mner face of the cylindrical container 10;

Arranged to slide for a limited distance through the lower portion of tube 13 is a soap discharge tube 22, the upper end of which is closed and interposed between the upper end of this tube and the cap 16- is an expansive coil s ring 23. Formed in the in-v termediate portion of this discharge tube 22 are apertures 24 which, when the tube is elevated to its limit of movement, coincide with the apertures 17. The lower end of this discharge tube 22 carries a disk 25, the

edge of which'is corrugated.

Formed in the lower portion of tube 13 is a slot 26 that is inclined slightly toward the right hand and passing through said slot and seated in the wall of tube 22 is a pin or "screw 27. 7

My improved soap dispenser as herein described may be sup orted in any suitable manner above or a jacent to a washbowl, but as shown in Fig. 1, I prefer to support the dis enser bv me'ansof a strap 28 t at is clampe around the lower portion of cylinder 10 and the end portions of said strap terminate in outwardly projecting brackets 29 that may be fixed in any suitable manner to the wall or to a support.

My improved soap dispenser 1s made ready for use by filling the chamber within cylinder 10 below the pressure plate 20 with soap in plastic or paste form and under normal conditions the spring 23 forces dis charge tube 22 downward to its limit of movement with the projectingend of pin or.

screw 27 at the lower end of slot 26. When the discharge tube is thus positioned, the apertures 24 are positioned slightly below and out of registration with aperture 17 in tube 13.

To bring about a discharge of a' small portion of the soap supply within the container the corrugated edge of disk 25 is engaged by the thumb and fingers of the hand with the palm ositioned directly below the discharge end of tube 22. Sutlicient pressure is applied to the disk to force the same upwardly and at the same time the disk is slightly rotated toward the right hand. As a result of these movements, discharge tube 22 is moved upward for a short distance within the lower portion of tube 13 thereby moving apertures 24 into registration with aperture 17 and as the tube 13 is partially rotated thefollower or pressure plate 20 toward the right will be drawn downward 'a slight distance as a result of its threaded engagement with tube 13 and the pressure thus applied to the top of the relatively soft soap mass within the container will cause a small portion thereof to discharge through the registering apertures 17 and 24, and this soap will discharge through the open lower end of tube 22 into the palm of the users hand. As soon as disk 25 is released, the pressure stored in coil spring 23 will act to move discharge tu'be 22 downward to its limit of movement and thus apertures 24 are moved out of registration with apertures 17.

The slot 26 that is traversed by pin 27 is purposely inclined toward the right hand in order to exert tendency or influence for the users hand to impart slight rotary motion hand when the disk 25 is engaged and moved upwardly and in this connection it will be understood that it is necessary to slightly rotate tube 13 in order to cause pressure plate 20 to move downwardly and apply the necessary pressure to the soap mass within the container.

In the form of device illustrated in Figs. 5 to 8 inclusive, sliding tube 22 is dispensed with and a disk 30 is secured to the lower end of threaded tube 13. Formed inthe center of this disk 30 is a soap discharge aperture 3" and pivotally mounted on a pin or screw 32 that is seated in the underside of disk 30 to one side of aperture 31 therein, 1s a plate 33 that normally closes aperture 31. A spring 34 is arranged on screw 32 beneath plate 33 and tends to force the latter against the under face of disk 30.

The annular wall 35 of a cup-shaped member 36 encloses disk 30 and seated in said annular wall and projecting into grooves 37 that are formed in the edge of disk 30 are pins 38. Occupying one of the grooves 37 and interposed between the pin therein and the end of said groove is an expansive coil spring 39. The outer end of plate 33 projects into a notch'or slot 40 that is formed in the wall 35 of cup-shaped member 36 and under normal conditions, or with spring 39 expanded, the cup-shaped member and plate 33 occupy positions as illustrated in Figs. 6 and 7 with plate 33 closing aperture 31. Formed in the base plate of cup-shaped member 36 is a relatively large aperture 41.

In the operation of the modified form of the dispenser, the hand is placed beneath the cup-shaped member 36 with the fingers and thumb bearing on the annular Wall 35 and said cup-shaped member is then rotated toward the right hand. As the cup-shaped member is thus initially rotated. the rear end of notch or aperture 40 bearing on the outer end of plate 33 will swing the same into the position shown in Fig. 8, thereby opening discharge aperture 31. When the inner end of plate 33 bears against the wall 35, the further rotary motion imparted to the cup-shaped member will impart rotary motion to disk 30 and the threaded tube 13 to which said disk is connected with the result that the pressure plate 20 will be moved downward a short distance, consequently forcing a small amount of the soap through apertures 17 and downwardly through discharge aperture 31 and thus the discharged soap is delivered into the palm of the users hand. As the cup-shaped member is released. spring 39 will cause the same to return to its normal position and in so doing plate 33 will return to its normal position, thereby closing discharge aperture 31.

Thus it will be seen a soap dispensing device that comprises relatively few parts and which may be easily and conveniently manipulated by one hand for the purpose of effecting a discharge of a small quantity of soap.

Obviously minor changes in the size, form and construction of the various parts of my improved soap dispenser may be made and substituted for those herein shown and described without departing from the spirit of my invention, forth in the appended claims.

I claim as my invention:
